Photorealistic boudoir portrait of a fictional adult woman, 28 years old, glossy black hair in a smooth high ponytail held with a plain gold band, smooth fair skin, polished makeup with soft plum lips, defined brows and a confident direct gaze, wearing royal-purple satin corset lingerie set with gold lace trim and a sheer charcoal robe slipped off one shoulder, standing in a room with one single oversized completely blank plaque on the wall behind her, warm gold side light, all surfaces completely plain with no letters, pictures or markings anywhere, elegant sensual atmosphere, soft cinematic light, tall portrait composition, high detail
